Lian Li Sx Low-Noise 3.1 1200w

Lian Li SX Platinum 1200W is a fully modular ATX power supply designed for high-performance PC systems. It supports ATX 3.1 and PCIe 5.1 standards for modern hardware. In addition, it features reinforced 12V-2×6 high-current terminals for compatible graphics cards. The PSU delivers up to 1200W of DC output. Its combined +12V output is rated at 1200W, while the combined +3.3V and +5V output reaches 100W. Furthermore, it accepts 100–240Vac input and uses Active PFC with a power factor above 0.95 under specified full-load conditions. The SX Platinum carries 80 PLUS Platinum and PPLP Platinum certifications. Moreover, Lian Li specifies conversion efficiency of up to 94% at 50% load. The power supply also supports power excursions up to 200% of its rated output. For cooling, the PSU uses a 120mm Fluid Dynamic Bearing fan with a maximum speed of 2000 RPM. In addition, its smart stop/start function enables fanless operation up to 40% load. This reduces fan activity during lower power demands. The SX Platinum measures 150 × 86 × 140mm. Therefore, its compact 140mm ATX depth provides broad case compatibility. It also features fully modular cables with braided sleeving and cable combs on selected cables. The PSU uses 105°C Japanese capacitors from Rubycon, Nippon Chemi-Con, or Nichicon. Furthermore, protection systems include OPP, NLP, OVP, SCP, OCP, OTP, SIP, and UVP.
